How to Control Banner Rate in Appodeal(sdkbox)

Hi.

I am developing one game using Cocos2d-x 2.2.6.
I integrated the Ad Banner using sdkbox and it works good.
Now I want to refresh banner ad every 30s.
How can I control it?

Please let me know if anybody knows about that.
Thanks

Maybe @dmitruss can help on this question.

As i know there is no way to control it currently. Refresh rate is absolutely controlled by the Appodeal itself.

Thanks for you help.
